  INTRODUCTION The market studies done by the various analyst on “Global market analysis on Turbine oil “forecast that the global turbine oil market to grow at a CAGR of 3.498% during the period 2017-2021 and the market size has a potential to grow by 1500.05 K MT during 2020-2024, and its momentum will accelerate during the forecast period. Turbine oil manufacturers are continuously working with OEMs to provide high-performance turbine oils to meets the rising demands globally. Nowadays the industries are more focused on extending the life of both lubricants and the equipment by implementing a robust  Reliability lubrication Program . In this article, we have tried to cover the maximum information about turbine oil which could help the power generation & manufacturing industries to move further with a cost-effective sustainable solution. TURBINE & ITS LUBRICATION SYSTEM The turbine which is the heart of the power plant extracts thermal energy from high-pressure steam and conve

Do’s : 1. Ensure taking a work permit from the site in charge and conduct a Tool Box Talk. 2. All electrical jobs to be conducted by a certified electrician. 3. Ensure all the equipment is flameproof. 4. Equipment that operates in three-phase power should have double neutral earthing. 5. The use of an Earth-leakage circuit breaker is a must for all the equipment. 6. The current rating for all equipment should not be greater than 30Amps. 7. Ensure use of proper rating Direct On Line Motor Starter in individual machines. 8. Ensure use of proper armored cables for the main power connection. 9. If there are cable lying on the road crossings or pathways should be covered and concealed to protect them from physical damage. 10. Cables without any joints should be used at all times. 11. Cables should be laid above the ground to the maximum possible extend. 12. Electrical connections should be kept clean, dry, and tight at all times. 13. Ensure all power supplies

*Test Parameters: 1. Viscosity 2. Viscosity Index 3. Flash Point 4. Pour Point 5. Demulsification 6. Copper Corrosion 7. Acid Number 8. Foam Characteristics 9. Oxidation Characteristics 10. Water Separation 11. Rust Prevention 12. Cleanliness 13. Water Content *Oxidation Stability Test :  Turbine Oil Oxidation Stability Test (TOST) is a valuable tool in order to indicate oil life for lubricants that are continuously exposed to gross water contaminations, high temperatures, and air entrainment in field service. ASTM D943 commonly referred to as Turbine Oil. Oxidation Stability Test (TOST), is widely used in the lubrication industry to evaluate the oxidation stability. *Best Practices for Steam Turbine Lubrication: 1. Keep Oil Clean, Cool and Dry 2. Install High Capture Efficiency Breathers to your Oil Respective Oil Tanks 3. Monitor returning bearing oil temperature regularly 4. Maintain proper alignment 5. Inspect for signs of foami

A) BSI (British Standards) – BSI BS 489:1999 –  Specification For Turbine Lubricants. B) DIN (German Institute for Standardization DIN 51515-1, 51515-2 –  This document specifies minimum requirements for oils for high thermal stress (high-temperature service) in turbines. C) ABB (ABB Group) ABB G12106 -  Ultra-clean turbine oil, Long-life, Rust & Oxidation-inhibited circulating oil. D) ASTM International – ASTM D4304  – Define the properties of the mineral and synthetic oil-based turbine lubricating oils that are functionally interchangeable with existing oils of this type, are compatible with most existing machinery components, and with appropriate field maintenance, will maintain their functionality. E) GE (General Electric) GE: GEK-32568 –  Lubricating Oil Recommendations for Gas Turbines With Bearing Ambients above 500°F (260°C) Also read:  https://www.linkedin.com/pulse/mandatory-properties-steam-gas-turbine-oil-anshuman-agrawal-mlt-1-/ We at  Minimac  study y

1. Steam Turbine Oil a) Good Demulsibility:  Means the ability to release water, This is important when the equipment is operating in humid climates or in a plant atmosphere that is wet or humid. b) Foam Suppression, and Air Release:  Foam is used whenever there is a possibility of liquid fire. The Foam will mix with water and then expand over the liquid that is on fire, cool the fire, and will finally suffocate it. c) Anti-rust protection:  Rustproofing is the prevention or delay of rusting. d) Anti-wear protection (Certain Cases) : Antiwear additives (AW additives) are lubricant components that chemically react with Oil to protect metal-to-metal contact between parts of gears. 2. Gas Turbine Oil a) Anti – Corrosion Protection:  Help protect the base oil from oxidation and the metal from damage by corrosive acids. b) Anti – Scuff (Certain Cases):  Anti-scuff additives are designed to react with the parent metal surfaces to provide protection under severe loa
